Connecting to your pump
The ideal flow rate for your pond is to pump the
volume of the pond water through the filter every
2 hours. To calculate your pond volume: average
length (ft) x average width (ft) x average depth
(ft) x 7.48 pond volume in USA gallons.
To calculate your pump’s flow rate, fill a container from the filter outlet hose at the pond
side. Time how long this takes in seconds, e.g. a 2 gallon bucket takes 12 seconds to fill.
Divide 3600 (the number of seconds in an hour) by the time taken to fill the bucket,
e.g. 12 seconds. Then multiply by the volume of the container, e.g. 2 gallons.
Therefore: 3600/12 = 300, 300 x 2 = 600gal/hr flow rate.
To increase flow, you may require a larger pump. If the flow rate is too high, use a valve to
reduce the flow.
The purpose of the pump is to transfer dirty water from the pond to the filter cannister.
Placing the pump at the opposite end to the filter outlet will provide the best results.
Pumps without foam pre-filters will allow for optimum filter performance.
Connecting the inlet/outlet hoses
•
Always secure the hose with a jubilee clip.
•
Warming the hose in a bucket of warm water can aid fitting.
•
Always ensure the smaller diameter hose tails are cut off and removed to prevent
poor UVC performance and flow rate from the outlet.
•
Use the shortest possible lengths of hose, in order to minimise flow restrictions.
•
Avoid folds and kinks in the hose, which will reduce flow and UVC performance.
IMPORTANT:
Do not exceed the maximum stated flow rate through the UVC filter –
see technical specifications table on page 4 for reference.

Installation guide:
The filter can be installed above or in the ground with water returning directly to the pond,
or via a waterfall, e.g:
